Take a step back to reflect. You're chronicling your life lessons, but what have you learned from them? Relay your intentions, desires, feelings of loss, feelings of joy, the wisdom you've gained, and other inner thoughts from time to time throughout the book. Taking a step back from the action of the story to reflect on what it all means is a good way to add depth to your autobiography.
This is an extremely emotional and intimate type of writing. You share a personal experience with your readers in a detailed manner. Your audience should have an opportunity to see the event or person that you’ve written about through your eyes and understand your feelings. Any personal essay has two main aspects: the description of a particular situation and how it has influenced your worldview and life. Generally, the personal essay is the shortest form of autobiographical writing, along with the essay for college.
Create an outline or a graphic organizer of the major topics and ideas you want to cover. For example, you might make a time-order chart -- a chart with event blocks to organize events chronologically. Or, you might draw a cluster web -- a diagram with connected circles -- to divide your autobiography into sections, such as one for relevant background information, one for life-changing events, one for special memories and one for goals and dreams. Focus on reasons why specific events, situations and circumstances were important to you and how they made you feel.
